The Throwing Circle: Lessons Learned in the Ring about Life, Success, and the Power of Coach-Athlete Relationships
When a coach and athlete are aligned, greatness can follow.
Luis Rivera was an unknown talent strolling through his small college cafeteria.
Dr. Charles J. Infurna was a curious volunteer coach still discovering his place in the profession.
Together, they persevered through challenges and found success in the hammer throwing ring, uplifting their respective lives in the process—including for years after Rivera graduated and moved on from track and field.
Readers get to see the detailed dynamics of the coach-athlete relationship, where trust, respect, and mutual understanding lay the groundwork for victory.
Dr. Infurna writes about his coaching career with vulnerability, from a frustrating first job that still managed to gain his interest in how he might get the best results out of all his athletes to learning how to mentor an elite thrower like Rivera. Along the way, Dr. Infurna had to question his own assumptions and find his self-confidence to see what it meant to be a “lightgiver.”
With the deft hand of a memoirist, Dr. Infurna peels back layers of growth in each chapter, personally and professionally, and shares the evolution of his coaching philosophy, forged by trials, failures, and ultimately, triumphs. Dr. Infurna blends a coach’s empathy and a researcher’s inquisitiveness with a sportsman’s passion to express the powerful influence of the coach-athlete dynamic on athletic performance, with perspectives that extend beyond the sporting fields.
Thoughtful and motivating, The Throwing Circle represents the meaning of mentorship, resilience, and the enormous opportunities that result when fate and dedication come together.
